This study was carried out on 7 cadaveric shoulders and was aimed to assess the effect of different clavicular anchorage points for the Lockdown™ device on the reduction of acromioclavicular joint dislocations, looking at the optimal location.  The joint was constructed using 4 different anchorage points and reduction was measured.

It was concluded that if the Lockdown device was secured at the level of the conoid tubercle, the AC joint could be successfully reduced anatomically in all cases.  If the device was placed medially or laterally to the conoid tubercle, the joint became increasingly more difficult to reduce.

This paper emphasises that correct positioning/placement of the Lockdown™ device is crucial to obtaining the best anatomical reduction.  The key position was at the level of conoid tubercle.
